External HDDs deliver 3–5× more storage per dollar than external SSDs, making them ideal for backups, media archives, and any workload where capacity matters more than speed. External SSDs are faster (10× at minimum) and more durable — better for active project files, video editing, and on-the-go use.
For PC backup: 2TB holds a typical PC's worth of data. For media libraries or gaming archives: 4–8TB is the sweet spot. For long-term backups or video production archives: 8TB+ gives room to grow. Larger drives typically offer better cost per TB.
